[Snort-users] PulledPork 0.7.0 not parsing enablesid, disablesid, modifysid or threshold.conf files when there are no rule updates

Thanks I've read the readme.

I didn't equate -P to parse disablesid.conf because -n indicated it would (but doesn't).

Am I reading things wrong?

Thanks!

OK that worked, so what's the -n switch for then?

-n Do everything other than download of new files (disablesid, etc). More info here: https://code.google.com/p/pulledpork/source/browse/trunk/README

Try running PulledPork with -P.

I'm testing PP 0.7.0 and seeing what looks like a bug but want to confirm it's not a config issue on my end.

As I tune the sensor I add entries in each of the config files (enablesid,disablesid,modifysid conf files) and then run pulledpork and restart snort

/usr/local/bin/pulledpork.pl -c /usr/local/etc/snort/pulledpork.conf -vv

If there are no rule updates to download (from either VRT or ET) I get this output

Next if I go into disablesid.conf and add another entry and re-run pp I get the same output as the first run - the new entry in disablesid.conf doesn't get parsed or disabled in the snort.rules file.

Any ideas?
